摘要： [Problem to be Solved]
Targeting mass production, the present invention provides an advanced method of manufacturing pure niobium plate end-group components from pure niobium plate material for superconducting high frequency accelerator cavity, wherein the invention is to convert the procedure/production method from the conventional machining or waterjet cutting followed by the conventional cold forging to the whole press-forming.
[Solution]
A method of manufacturing pure niobium plate end-group components for superconducting high frequency accelerator cavity used for the acceleration of charged particles, composing of
(1) shear-blanking procedure of the pure niobium plate different from the conventional fine blanking, wherein the clearance is set to be very small value below 0.5% of pure niobium plate thickness to form a near net shape semi-product free from foreign objects on and below the material surface under the restriction of the material on binding tool to generate counter force, and
(2) forging procedure at different temperatures from any of the conventional hot or warm or cold forging, wherein press forging is conducted to be free from the occurrence of blue brittleness/necking and to bring about prominent metal-flow, formability, the size accuracy in any portion of a product and the margin of further press-forming by controlling forging temperature to be below 200°C and beyond ambient room temperature,
and characterized in that
manufacturing method such as full machining or waterjet cutting followed by cold forging of the pure niobium plate end-group components is converted to the whole press-forming method.

摘要： End-group components for superconducting accelerator cavity used in acceleration of charged particles are manufactured by subjecting pure niobium sheet materials to press forming composed mainly of flat-bottomed cylindrical drawing, preferably by simultaneously conducting control of slide velocity and / or its motion and control of tool die temperature and / or its distribution / gradient in the above press forming, further preferably by dynamically controlling blank holding force in accordance with the variation of flange area, flange thickness and deformed characteristics of niobium sheet materials during the press forming, more preferably by preparing an anisotropically shaped blank instead of a circular blank by use of servo press forming machine, servo-die cushion temperature control equipment, water-soluble solid coating type lubricant, and a tooling die.
